Fotovoltaik-termoelektrik hibrid sistemlerinin termoelektrik modüllerinin verimlerinin arttırılması

The consumption of fossil fuels outcomes to greenhouse gases that brings out global warming of the World's atmosphere and nearby to climate change. Under the surface are hidden costs such as security expenses, clean-up efforts, air pollution, environmental damage, war-related expenses and other additional hidden expenses. Sources of Renewable energy are especially very good energy sources to battle against global warming. Energy from Sun, is a shining renewable energy source, especially for the regions with high solar irradiance. After the Oil Crisis, happened in 1973, the researchers especially focuses on photovoltaics. Till now the scientists are focusing on improving the effieciency of solar cells and photovoltaic modules. PV-TE Hybrid Systems are especially one of the shining systems of new type of systems, to enhance the module efficiency. Combining photovoltaic (PV) and thermoelectric (TE) modules into PV-TE systems has shown great promise for maximizing the use of the sun's spectrum, boosting overall power output, and lowering the amount of area needed for PV power plants. With my thesis I focused on enhancing the efficiency of a practical PV-TE system model. Usually, a significant temperature differential is produced across the thermoelectric generator (TEG) module utilizing a variety of heat removal techniques in order to increase the power output of the TE component. These cooling systems makes increase, in performance of TEG module, however, concurrently, they rise the electrical performance of PV. In this thesis, I assessed the performance of PV-TE systems using seven different TEGs and monocrystalline silicon solar cells in four different scenarios. According to Standard Test Conditions EN/IEC 61215, the PV-TE hybrid systems are first tested at 25 °C without a cooling device. We then assess the systems using a passive cooling strategy, improving heat dissipation with aluminum heat sinks. Additional evaluations use an active cooling (AC) system with coolants of water and nanofluid in succession. The evaluations' findings are intended to set a standard for raising the effectiveness of upcoming PV-TE systems.
